Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to a duplex basket strainer arrangement.  Such arrangements include an outer casing having a first basket strainer receptacle at one end thereof, a second basket strainer receptacle at the other end thereof, a center plug receptacle having an inner wall surface and being disposed between the first and second receptacles, inlet means disposed in one side wall of the casing for permitting entry of a fluid into the casing, and outlet means in the other side wall of the casing for permitting exit of the fluid from the casing and a center plug disposed in the center plug receptacle. In accord-ance with the invention, the center plug comprises an elongated member, circular in cross-section, having an inflow stage and an outflow stage, and resilient means disposed around the periphery of the elongated member between said inflow and the outflow stages.          The diameter of the resilient means is greater than the diameter of the inner wall surface of the center plug receptacle adjacent the resilient member, so that the resilient member resiliently engages the inner wall surface to provide a fluid tight seal be-tween the inflow stage and the outflow stage.

Abstract: ABSTRACT OF THE DISCLOSURE         A play gym comprising a horizontal bar from which swings and other rides are suspended is supported at its opposite ends by pairs of legs.  Special three-axis pivot joints connect the pairs of legs to the horizontal bar which permit each pair of legs to be folded together and against the horizontal bar so that the gym can assume a stick-like con-figuration.  When the legs are unfolded to support the horizontal bar, clam shells forming parts of the pivot joints clamp around the ends of the horizontal bar thereby preventing end-wise movement and racking of the play gym.  Provision is also made for substituting one pair of legs by a horizontal pivot arrangement which can be secured to a vertical support so that the gym can be used in a small area and be foled up out of the way against the support when not in use.  Also the swings and other rides associated with the gym are foldable so that they can also be stored in a minimum amount of space when not in use.

Abstract: ABSTRACT OF THE DISCLOSURE      A bicycle having front and rear wheel caliper brakes each being connected by a cable to a lindage including a swingable cam element which is normally disposed in the path of travel of a cooperating cam member mounted for movement concentrically about the pedal axle whereby the cam element through its swingability is removed from such path during forward pedaling action and is lockingly engageable with such cam member upon back pedaling action.  In the latter condition force is applied to the linkage for effecting a pull upon the cables to effect braking operation.  The cam members are so related to the pedal cranks that when engagement with the cam element is effected one pedal crank will be downwardly directed whereby a support stand carried upon the associated pedal may cause such pedal to swing to present the support stand for engagement with the support surfaces.

Abstract: ABSTRACT          Conventional multi-needle tufting machines may be modified and provided with the special looper element of the present invention so that without backdrawing or robbing from a previous loop a row of stitching is formed to provide a pattern of any number of high cut loops and low cut loops.  The looper element is reciprocated by the conventional mechanism and the loops are cut by long and short knives reciprocated by the conventional knifebar on the machine.  The looper element may be made from flat plate in one plane to provide a support portion and a closed end, like a nose with an internal space, which enters the loop.  A bottom member like a finger on the nose and a top member defines the internal space which is substantially closed by means of the bottom member except for an offset entrance having a small angular configura-tion.  The small angular entrance leads to the space in the looper element in which a short loop supplied by a pattern control means is confined until cut.  The long loops slide around the nose and along the bottom member without entering the notch and are cut by a short knife whereas the short loops inside the element are cut by a long knife.

Abstract: ABSTRACT OF THE DISCLOSURE     A method of loading and unloading a vessel with heavy objects is described whereby an object is vertically lifted, for instance from a vehicle drivable on a quay, by means of a crab, gantry or the like which together with said object is moved horizontally along girders from the lifting position to a position above the hold of the vessel. Said girders are arranged on  the quay, extending in a cantilever manner out beyond the edge of the quay substantially up to the adjacent edge of the hold. From said cantilever girders the crab together with the object is moved over to and along horizontal extensions of said girders. These extensions, which are entirely supported by the vessel, bridge the hold. When the crab with the object has reached a suitable position on said extension and above the hold, the object is lowered into the hold. Also described is an equipment intended for carrying out said method into effect.

Abstract: ABSTRACT OF THE DISCLOSURE     A function control code sequence of signals, each comprising a pair of audio frequency tones, is transmitted from a control location to a remote station selector.  Each input signal is applied to a tone decoder element which separates the two tones through a filter, amplifier, detector network to produce a pair of logic signals representing the tones received.  The sequential pairs of logic signals are applied to a code selector which converts the 2 of 7 format into a 1 of 12 digital code sequence equivalent to the original function control code selected at the control location.  This digital sequence is applied through a programmable cross bar connector matrix to a sequence detector responsive only to a predetermined input sequence.  The matrix is programmed to produce this predetermined sequence and actuate the sequence detector only when an assigned function code is received. When the sequence detector is actuated, its output is applied through another matrix to a pulse generator which produces an output pulse to  actuate the desired function control.  Each output pulse is also applied to the tone decoder to enable an analog switch which completes a feedback path for one of the input bandpass filter, compression amplifier networks.  When the feedback path is complete, the filter, amplifier network oscillates at a preselected audio frequency to transmit an answerback signal to the control location to indicate that the transmitted function has been registered.

Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed is a method for recovering hydrocarbons from a subter-ranean formation.  A heated fluid is injected into the formation by means of a perforated conduit which is positioned substantially horizontally through the formation to heat hydrocarbons within the formation.  After a suitable heating period, injection of heat is terminated to permit fluids including formation hydrocarbons to drain from the formation into the conduit.  The drained fluids within the conduit are then heated to a temper-ature such that at least a portion of the drained fluids are vaporized.  These vaporized fluids pass from the perforated conduit and into the forma-tion to further heat formation hydrocarbons.  Subsequently, formation fluids of reduced viscosity are recovered from the formation through the perforated conduit.
